Demi Moore, 50, has started dating 31-year-old restaurant entrepreneur Harry Morton, sources exclusively tell Page Six. The two were seen holding hands Saturday while visiting the Stanley Kubrick show at LACMA, along with pals including Russell Brand, who posed for photos with visitors at the LA museum. Morton is the handsome Hard Rock Cafe heir and founder of Pink Taco restaurants. He and Moore, who we’re told have known each other for years, have gotten closer in the past few weeks.
